Is it possible to create an action that would only work on specific file types? For instance, exporting album art from files with .m4a extensions only (ignoring .mp3, .wav, etc.). I know I can accomplish this manually. Just wondering if there's a way to fully automate the task. Thanks!

The easiest way would still be to filter for such conditions.

Then as rule of thumb: you can do that for almost any action that allows a format string unless the format string describes a mandatory parameter. A filename would be a mandatory parameter.  
Having a particular field or not is not mandatory, so that should work.  
You would have to repeat the condition in every format string.  
So I still think that the filter is the easier way.

Ok, that is helpful. I hadn't thought about using the filter. That should make the task easier. Thank you!
